They are available in a number of wheel options for maximum performance flexibility. Produced in an ISO 9001 Certified facility. Listed by Underwriters Laboratory (UL 705) and UL Listed for Canada (cUL 705).

3 Rotatable housing is standard on all models. Discharge flanges are standard on all belt drive models, except in downblast or bottom angular down discharge positions (see page 17).Belt DrivesBackward Inclined Flat Blade wheel : CPS, CPA & CPVL icensed to bear AMCA Certified Ratings Seals for Air and Sound 762 listing for restaurant applications wheel / Steel Scroll (CPS)Aluminum wheel / Aluminum Scroll (CPA) wheel Sizes: 10 - 49 Capacity: 70 - 49,150 CFM Static Pressure: 1 - 8 Class I or Class II (size 120 - 365) CPA is Spark Resistant Type A construction(see page 20)Aluminum wheel / Steel Scroll (CPV) wheel Sizes: 10 - 49 Capacity: 50 - 43,400 CFM Static Pressure: - Backward Inclined Airfoil wheel .

5 CPS uses a welded, LorenizedTM steel wheel , with backward inclined flat blades. CPA uses a welded, aluminum & CPFB use a steel wheel , with forward curved WheelsCPS-A uses a welded, LorenizedTM steel wheel , with backward inclined airfoil blades. CPA-A uses a welded, aluminum shown. All belt drive units use this body type:Backward Inclined Airfoil: Has the highest efficiency of all of the centrifugal impeller designs with blades of airfoil contour curved away from the direction of rotation. Air leaves the impeller at a velocity less than its tip speed.

6 Relatively deep blades provide for efficient expansion with the blade passages. For the given duty, the airfoil impeller design will provide for the highest speed of the centrifugal fan Inclined Flat Blades: Efficiency is slightly less than that of the airfoil design. Blades are single thickness metal inclined away from the direction of rotation. Air leaves the impeller at a velocity less than its tip speed. Relatively deep blades provide efficient expansion with the blade Curved: Efficiency is less than airfoil and backward curved bladed impellers. Has blades with both the heel and tip curved forward.

7 Air leaves the impeller at velocities greater than the impeller tip speed. For the given duty, the wheel is the smallest of all of the centrifugal types and operates most efficiently at lowest Centrifugal FansA centrifugal wheel brings air in parallel to the axis of rotation and discharges air perpendicular to the axis of rotation. The air then follows the shape of the fan to the outlet.
